50. Deadly Attacks Against The Assyrian Christians Of Iraq Barhebraeus has quoted from a Syriac work of thabit ibn qurra, where he praisesthe Harranians for their loyalty to the ancient religion and contribution to http://www.christiansofiraq.com/harranian.html

Christians of Iraq Contact Assyrian Contributions to the Arab Civilization The Haranian School Harran during the Assyrian period was an important center of astronomy and mathematics which was used to calculate the movement of planets the prediction of eclipses and other astronomical events. It should not surprise us that such knowledge had survived a thousand years later in that city perhaps because Harranians refused to convert to Christianity and the planetary worship was still part of their religion which made such knowledge necessary. During the early Islamic period they were called Sabians a name mentioned in Koran which they adopted to join the ranks of the tolerated people. At times they have been confused with the Sabians living in southern Mesopotamia. One of the first translators of the Harranian school of mathematic and astronomy is known by his Arabized name as al-Hajjaj ibn-yusuf ibn-Matar (786-833). He is credited with having made the first translation of Euclid' Elements and one of the first of ptolemy's astronomical work in Arabic "Almagest" in 827-28 from a former Syriac version. (Philip Hitti, "History of the Arabs", Princeton University Press, 10th edition, Macmillan st. Martine Press p.314) It was revised by Hunayn ibn-Ishaq and later by Thabit . Thabit bin Qurra (826-901) is considered to be the greatest geometer of the Arab period. "Thabit translated into Arabic seven of the eight books on conic sections of Apolonius and wrote earliest known work on the sundial."

timeline home courses topics theorems ... timeline Around 30 000BC to 5000BC. We have the findings of some kind of mathematical pursuit, from recording the number on bones, to early geometrical designs. Around 4000BC to 2000BC. Babylonians and Egyptians developed calendars and began using them. Around 1900BC one of the two mathematical papyri is written - the Moscow Papyrus (also called the Golenishev papyrus) giving details of Egyptian geometry. Between 1850 and 1750BC Babylonians know of and use what we now call Pythagoras' theorem. They also compiled tables of square and cube roots. About 1700BC the Ahmes (or Rhind) papyrus is written. It shows number work of Egyptian scribe, in particular dealing with fractions. Around BC Thales of Miletus develops an abstract geometry, elevating it from the measurement of surfaces and solids to the first use of logical proof. If at all, Pythagoras of Samos lived sometimes between 50 th and the 52 nd Olympiads, or between 580 and 568 BC. He founded a school at Crotona , teaching that numbers are the cause of the various qualities of everything that surrounds us About 450BC Greeks begin to use written numerals and Zeno presented his paradoxes 387BC Plato founds his Academy in Athens. Plato thought that there was an ideal world in which ideas of everything that exist in our world are created. We try to re-create these ideas in our everyday world by creating things, but they can never be as perfect as the 'ideals' of these things. He identified five regular polyhedra, which are now called

The Islamic spirit produced a radical transformation in the Arabian Peninsula, as well as among the countries where Islam took firm root in the immediately succeeding centuries. The rich contributions which Islam has made in the various branches of Science served as the basis for the development of modern science. Although many earlier western historians tended to ignore this fact, recent investigations have led to a wider recognition of the importance of the Muslim contributions, especially to the development of scientific thought and the scientific method.

La matematica del mondo islamico * Home Arte e Cultura Immigrazione Islam ... E - Mail Gli Arabi, ovvero i matematici del mondo islamico che vissero tra il nono e il quindicesimo secolo, non furono semplici traduttori degli scritti greci di matematica, ma, come dimostrano studi recenti, elaborarono molte parti della matematica che poi ricomparve in Europa tra il Cinquecento e il Settecento. Sino a tempi recenti la maggior parte degli storici della matematica conti nuano a rifiutare l'ipotesi di qualsiasi contributo originale del mondo islamico allo sviluppo della matematica sia omettendo di riportare le loro scoperte sia accettando quasi acriticamente l'opinione del filosofo della scienza Pierre Maurice Duhem per cui la scienza araba non avrebbe fatto altro che riprodurre quanto le era pervenuto dalla traduzione dei matematici dell' antica Grecia e consegnarlo ai matematici europei. In questo modo, il cammino della scienza, in particolare della matematica, si sarebbe interrotto per circa 1000 anni, per poi riprendere dal punto in cui i Greci l'avevano lasciata.

Zeer bedankt voor uw steun! Thabit ibn Qurra Thabit ibn Qurra abu' l'Hasan ibn Marwan al-Sabi al'Harrani (?) te Carrhae in Mesopotami« (nu Harran in Turkije 18 februari te Baghdad ) was een arabisch astronoom en wiskundige . In het Latijn wordt hij ook Thebit genoemd. Thabit, zoon van Qurra, was een telg van de Sabijnen van Harran. Deze clan aanbad de sterren en was buitengewoon ge¯nteresseerd in astronomie en wiskunde , alsmede de werken van alle bekende volkeren op dat gebied. Het is dus niet verwonderlijk dat Thabit in Baghdad ging studeren in het Huis der Wijsheid op uitnodiging van Mohammed ibn Musa ibn Shakir Thabit en zijn latere leerlingen leefden in een van de meest opwindende tijden uit de geschiedenis van de Arabische wetenschap . En niet alleen dat, hij woonde in Baghdad op het wetenschappelijke hoogtepunt van die stad. Levend op het kruispunt van de oude, Griekse wetenschap en wetenschap uit het oosten (zoals het huidige India ) en met een leenheer die de ontwikkeling van zijn interesses steunde, had Thabit toegang tot de rijkste verzameling kennis van over de hele bekende wereld en de beste onderzoeksmiddelen die er te krijgen waren. Bovendien sprak hij van huis uit Syrisch, toen nog een oost-Aramees dialect van Edessa, en sprak hij ook goed Grieks.

The Garden of Archimedes A Museum for Mathematics Pythagoras and his Theorem Another very simple demonstration. visual demonstration and Airy's explanation demonstration of Thabit Ibn Qurra The white area with the two yellow triangles forms the square of the hypothenuse, while with the two green triangles, equal to the previous ones, gives the squares of the cathets. Naturally, even here the visual evidence must be supported by a demonstration, which can be performed by anybody. It seems that the previous demonstration was found in 1855 by G. B. Airy , the Greenwich observatory astronomer from 1836 to 1881. In the white part of the figure, Airy wrote the poem that follows: I am, as you may see, a + b When two triangles on me stand, But if I stand on them instead, The squares of both sides are read. The demonstration of Thabit Ibn Qurra. The following demonstration is attributed to the Arab mathematician Thabit Ibn Qurra (826-901). Starting from the right angled triangle ABC we make an irregular polygon ABDGLA by adding to the triangle the squares on the cathets ALHC and CBDE and the rectangle HCEG. This last one is divided by the diagonal GC in two right angled triangles, equal to the triangle ABC. Let now LI equal to BC and FD equal to AC; also the triangles ALI and BFD are equal to ABC. The same is true for the triangle IGF, because we have GI=AC and GF=BC. .
